ly ofthe cooler, thereby permitting a new block pf solid carbon dioxideto be inserted into the container without opening the cooler.

Another object of the invention is to provide a water cooler in whichgases formed by the evaporating solid carbon dioxide may be led throughselected tubes leading from the container and this gas discharged eitherin'- ternally or externally of the cooler.

Another object ofthe invention is to provide a cooler ofV this characterwherein one of the tubesis formed into a coil about the container forthe solid carbon dioxide and provide the container with means forcontrolling flow of gas through the tubes adapted to be adjusted byactuating means carried by a removable cover for the outer-end of thecontainer, thereby permitting flow of gas through the container andtubes to be very easily controlled and the temperature of the water inthe cooler regulated. s

' Another object of the invention is tonot only permit flow of gasthrough the con-` tainer to be regulated, but also permit the block ofsolid carbon dioxide to be disposed either in spaced relation to theinner end of the container or pressed firmly into engagement with theinner end of the container when very cold water is desired.

Another object of the invention is to permit the gas which escapes fromthe tubes within the cooler to be directed downwardly towards the bottomof the water container and bubble up through-the water therein in orderto 4carbonize the water or allow the gas to pass olf into the contlainerwithout passing through the water and also pass downwardly into 4acompartment below the water compartment in which bottles of beverages orfood are tobe placed and cool this second compartment. f

mit gas to be delivered xteriially of the cooler from the tubes througha pipe which may be placed in a glass filled with water,

thereby causing the water in the glass to be carbonized without all ofthe Water in the coolerbecoming carbonized. Another object of theinvention is to so Another object `of the in entlion. is to perform theupper portion of the cooler that a,

bottle of large capacity maybe set in place 1n an inverted position inorder to replenish water in the water compartment of the cooler as it isdrawn olf, and prevent warm air from entering the water compartment ofthe cooler.

The improved Water cooler indicated in general by the numeral 1 isdivided by a `Vpartition 2 into an upper chamber 3 and a lower chamber 4which has communication with` the upper chamber through a pipe 5 and hasa door 6. This dpor may be hingedly mounted in any desired manner sothat Laccess may be had to the lower compartment in order that bottlesof beverages or food may be placed in or removed from the lowercompartment.

Within the upper chamber, which may be referred to as a watercompartment, is disposed a crock or water container 7 which ma e formedof any suitable material and pre erably has a capacity of aboutthree-,fourths of a gallon although it may have any capacity desired; VAfaucet 8 leads `from near the bottom of the crock 7 through a wall ofthe cooler and near the to ofthe crock is provided a distributer 9 w 'chalso extends outwardly through the wall of the cooler abbve the faucet8.

A container 10 for a cooling medium, which is preferably solid carbondioxide, is disposed transversely in the lower portion of the 05 crock'and extends from the same through an opening 11 formed in a wiill ofthe cooler.

-This container for the cooling medium may project through either a rearwall or sidewall of the cooler, but will preferably project through aside wall so that access may be had to the outer end of the containerwithout movf ingthe cooler in case it is placed in a rooni against awall. Itshould also be noted that the container for "the cooling mediummay project 'outwardly ,through a wall of the cooler either at a sideopposite the faucet 8 and dstributer 9, as shown in Figure 1, or atright angles thereto.

The openupper end of the cooler is provided with a head 12 which fitsrmly into place and has its central portion formed with a depending well13 from the bottom of which extends a neck 14 which projects through anopening formed centrally of the cover 15 for the container 7 and fitssnugly into the `de pending neck 16 of the cover. Therefore, when alarge bottle 17 which serves as a reservoir for vwater is set in aninverted position upon a cushioning ring 18 about margins of the well 13the neck of the bottle will extend downwardly through the neck 14 andinto the neck 16. The neck 16 is of such depth that it projectsdownwardly below the bottle neck and, therefore, when the crock 7 isfilled with water to the height shown in Figure l, a water seal will beformed about the lower end of the neck 16 and warm air vwill beprevented from entering the crock through the neck 16 and also excludedfrom the chamber 3 as the water level is lowered and thecrock refilledfrom the bottle.

The container for the cooling medium is constructed as shown in Figure 2and has an outer shell 19 formed of metal which will not corrode orrust. This shell 19 is closed at its inner end by alhead'20 and itsouter end portion 21 is externally threaded for engagement by a securingring 22 and internally threaded for engagement by the threaded inner endof an extension or neck 23 formed of bakelite or any other heatinsulating material found suitable. A collar 24 is formed aboutvtheouter shell near its outer end for engage-I ment by a gasket 25 and,therefore, when the threaded outer end portion of the shell is passedthrough an opening 26 formed in the crock `Tand the securing ring 22applied, a water-tight joint will be fornfed. The neck or extension 23projects outwardly through 'the opening 11 in the cooler 1 and carries asecuring ring 27 which bears against a rubber gas et 28 and forms atight joint. The neck 23 projects outwardly beyond the securing ring'ornut 27 in order that a cap or closure for the outer end of the containermay be ap lied. l l

n inner shell 29 formed of heat insulating material such as bakelite,fits into the outer shell'any has its inner end portion reducedthickened inner end portion 31 of the outer shell.` A slot 32 whichextends circumferentially of the outer shell is formed in the thickenedinner end portion 31 thereof and provided with a mouth or entrance 33intermediate its ends so that a pin 34 which projects from the reducedinner 'end portion 30 of the inner shell lmay be passed through themouth and engaged in the slot to retain the inner` shell in its properposition in the outer shell and limit rdtation of the inner shell. a

A recess or pocket 35 is formed in the thickened portion 31 of the outershell and the inner end portion of the inner shell is fimed with a slot36 which is disposed out of registry with the recess when the innershell is in the positionsshown inFiguresg 6 and 7, as shown in Figure10, andmoved into registryr with the recess, as shown in Figure 11, whenthe inner shell is moved towards the positions shown in Figures 8 and 9.The outer end portion of the outer shell is offset or internally.reduced in thickness and Vformed with\opposed openings 37 and (38 whichcommunicate with bosses or sockets 39 and 40, and while these socketshave been shown projecting from upper and lower portions of the outershell it will be understood that they could project from side portions.

A collar 41 is formed4 about the outer end portion of the inner shelltofit snugly against walls of the outer shell and close the outer end ofthe space 42 between the inner and outer. shells,y and through thecollar are formed openings 43 and 44 which`are spaced from each otherless than one-half the cire outer shell that when the inner shell isturned u cumference of the inner shell. is also formed with -recesses 45and 46 which are spaced from each other a distance corresponding to theydistance between the'openings 43vand 44 and so located with respect tot-he openings formed in the inner shell and from the position shown inFigure 6 towards that shown in Figurey 9, the opening 44 will move intoregistry with the opening 38 when.

the opening 43 is moved out of reglstry with the opening 37, and therecess 45 then moved into registry with the opening 37 after which therecess 46 vwill move into registry with the opening 38. These successivepositions are clearly shown in Figures 6 through 9.

In the sockets39 and 40 are lscrewed nipples 47 and 48 carried by tubes49 and 50,

and, by referring to Figures 1 and 2, it will be seen that the tube g49leads directly from p the' socket 39 to the distributer 9 whereas thetube 50 is formed into a coil '51 about the container 1'0 and thenextended upwardly to the distributer. By this arrangement, water in thecrock will be slightly cooled when the inner shell is in the positionshown in Figures 2 and 6 by the cold gas'passing through the openings 43and 37 into the tube This collar 49. When the inner shell is moved intothe position shown in Figure 7, the opening 37 is closed and the opening44 moved into registry with theopening 38 and the-'cold gas through thetube 50 to the distributer. Therefore, the water will be reduced to Jalower temperature as the coil serves very effectively as a cooling coil.By turning the inner shell to the position shownr in Figure 8, therecess 45 will Vbe moved into registry with the opening 37 and bylthis'time the slot 36 willvhave been moved from the position shown .inFigure10-towards that of Figure 11 to such an extent that it will partiallyoverlap and register withA the recess 35. Therefore, the gas `will passthrough the slot 36 and recess 35 into .the space 42`between the innerand outer shells and u,through the recess .or passa e 45 into the tube49. The water will not on y be slightly cooled by the tube 49, but sincethe gas passes betwee the two shells the outer metal shell willbeKchilled and permitted to serve greatly as a cooling element for waterin the lower portion of the crock. When the The distributor 9 consistsof a tubular bodyv or pipe 52 whichjextends through an opening formed inthe wall of the cooler and is provided with a collar 53 to bear againstthe outer face of the wall and limit its inward movement 4when asecuring nut 53 is applied and tightened, whereby the distributera willbe firmly held in place. The tubular body projects into the crock 7 andhas a coupling 54 screwed tightly upon its threaded inner end.

This couplingfis formed with a chamber 55 having side openingsin whichare screwed nipples 56 Vand 57 at the upper ends of the Ans tubes 49 and50 and therefore gas passing through either tube will be delivered intothe chamber 55. An outwardly opening check valve 57 in the nipple 57controls flow o f gas through this nipple and the tube 50. Openings 56aand 57a are formed in the pipe 52 td register with openings 58 and 59formed in the coupling 54 and in these openings 58 and 59 are securedtubes 60 and 61.

The tube 60 extends upwardly through the cover15 of the crock andtherefore when the gas is delivered through the tube it may lill theinterior'of the chamber 3 about the crock j and pas/s downwardly throughthe pipe 5 into the lower chamber or compartment 4 to cool said lowerfood compartment. Suitable vents may be provided to permit the gas toescape from the lower compartment -to the c atmosphere or any othermeans provided for permitting the gas to eventually escape. The tube 6lextends downwardly to a position near the bottom of the'crock and if gasis passing through this tube it. will bubble up through the water in thecrock and carbonize w the water. The gas after passing through thewater, passes out of the crock, its cover fitting, snugly but not airtight, and will pass through the pipe 5 into the lower compart-' nient.'It will thusbe. seen that water in the crock may becarbonized or remainin its original condition. In order to control the pas` sage of gasthrough the tubes 60 and 6l, there has been provideda valve inthe formof a sleeve 62 which fits snugly in the pipe 52 and is retained in placeby a cap 63 screwed upon the threaded outer end portion ofthe pipe ortubular end 52. w

This tube 62 is formed with an opening 64 near its inner end which maybe moved into registry with either the opening 58 or the opening 59.Under normal conditions the opening 64 is disposed in registeringrelation with the opening 56a and therefore the gas will pass throughthe pipe or tube 60.

A stem or actuating rod 65 is provided for rotating the sleeve 62 andprojects outwardly therefrom a slot 66 formed in the pipem52 be- \tweenthe collar 53 and the cap 63. When j the opening 64 is in registry withthe opening 56a the operating stem' will/be disposed vertically midwaythe length of the slot 66.

The stem may be moved towards one end of the slot to move the opening 64into register with the opening 57 or it may be moved to- Wards theotherend of the slot in which position the opening 64, willnot register witheither of the openings 56 `or 57". When the valve sleeve is in thelast-mentioned position, an opening 67 formed near its outer end willregister with a side opening 68 forining a continuation of the bore of aneck 69 on the cap 63 to which a tube 70 is connected'and the gas willthen pass through the tube 70 and may be Vdelivered into a glass 7lfilled with water and resting upon a glass supporting bracket 72 carriedby the cooler below the faucet'8. It shouldbe noted that the tube 70 isprovided intermediate its length with a fiexible section 73 formed ofrubber tubin in order that the tube may be easily movedh into or out ofthe glass and not interfere with placing a glass upon the bracket 72.

Within the inner shell of the container 10 is disposed a cylindricaljacket 74 which has its outer endk portion thickened externally to forma collar 75 to bear a ainst a circumferentially extending shoul er 76formedin the inner shell. A groove 77 extends circumferentially aboutthe collar 75 and from this groove leads a notch 78 so that a pin 79projecting from the circumferentially extending iange80 at the outer endof the inner shell= shell and guide the turning of the jacket.

Openings 81 and 82 are formed in the acket to register with the openings43 and 44v formed through the collar or annular shoulder 4l of theinnershell. Therefore gas may escape from within the jacket and the innershell to reach the openings 37 and 38 when the inner jacket is in thepositions shown in Figures 6, 7 and 10 and the slot 36 out of regi strywith the recess 35. A,

`Within the jacket is disposed a follower 83 secured to the lower bar 84of a yoke' 85 which is of suiicient length to project from oppositesides of the follower and engage through slots or passages 86 formedlongitudinally of the jacket in opposite sides thereof. Each of theseopenings has rack teeth 87 along one side edge and at opposite ends ofthe lower bar of the yoke are formed fingers 88 to engage the rack teethand releasably hold the follower in a set position and prevent it frombeing moved longitudinally in the jacket by the coil spring. 89 whichextends longitudinally in the jacket and has one end firmly secured.tothe follower and its other end engagedlby a screw 90 carried by thehead 91 closing the outer end of the jacket. The screw 90 will be firmlyheld in place as it extends into a knob 92 by means of which the jacketis to be inserted into the inner shell or removed therefrom. l

A shield 93, formed of bakelite or other heat insulating material,prevents the follower from contacting with a block of solid -carbondioxide fitted into the jacket and thereby wastefof the carbon dioxideis prevented. The follower should be retained in a retracted positionwhile the block of solidcarbon dioxide is beingl set in place and thejacket fitted into the inner shell, and in orderto do so each slot 86has its outer end portion widened, thereby providing each slot with aside extension or shoulder 94 upon which ends of thelowerbar 84 may restand retain vthe followerin its retracted position.

The end bars 95 of the yoke 85 fit into grooves 96 formed longitudinallyin the walls of the inner shell to guide sliding movement of thefollower, and the pin 79 is located at such va distance from one of saidgrooves that when the j acket is inserted into the inner shell and theend bars of the yolte engage \in the grooves, it is necessary to turnthe jacket a short distance in 'order to permit the pin to pass throughthe notch 78 and engage in the groove 77. During this initial turningmotion the end bars will be moved off the shoulders 94 and across theslots 86 to such a position that the fingers 88 will be engaged with.the fingers of the racks 87.
